ODBC data sources can be used by all SQL Anywhere client interfaces except jConnect and Sybase Open Client. The data source
is stored in a file on Unix and Windows Mobile operating systems.

If you have a data source, your connection string can name the data source to use:

Data source
Use the DataSourceName (DSN) connection parameter to reference a data source in the Windows registry:

DSN=my-data-source

File data source
Use the FileDataSourceName (FILEDSN) connection parameter to reference a data source held in a file:

FileDSN=mysource.dsn

Note

When creating a connection string, it can contain the name of an ODBC data source that contains connection parameters, and
connection parameters that are specified explicitly. If a connection parameter is specified in the connection string and in
the ODBC data source, the value that is specified in the connection string takes precedence.
